The TIOCMBIS, TIOCMBIC, TIOCMGET, and TIOCMSET ioctls are described on the termio(7I) man page. The other two look like non-portable Linux-specific features. Unless you write your own driver, you won't be able to do much with those. Of them, I see no real point to TIOCGICOUNT. I'd expect interrupt counts to be provided through some sort of diagnostic interface, such as kstats, rather than through an application interface. TIOCMIWAIT, though, sounds like an interesting addition. The best you can do for TIOCMIWAIT is to open the /dev/cua/ node in blocking mode in order to wait for DCD assertion. There's no way to wait for any of the other input signals (such as CTS or RI). -- James Carlson 42.703N 71.076W <carls...@workingcode.com> _______________________________________________ opensolaris-code mailing list opensolaris-code@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
